Meta bets on four MTIA chips to scale its AI workloads by 2027

Meta plans to roll out four generations of in-house AI chips—MTIA 300, 400 (Iris), 450 (Arke), and 500 (Astrid)—by 2027 to power its expanding AI workloads, diversify away from relying solely on external GPUs, and cut costs. MTIA 300 is already used for content ranking, MTIA 400 has completed lab testing, and the later models are slated for mass deployment, while Meta continues buying GPUs from Nvidia and AMD to complement its custom silicon.
